Algebra Notes
Basic Algebraic Laws Communicative Law For Addition: a + b = b + a ex. 5 + 7 = 7 + 5 =12 Communicative Law For Multiplication: a x b = b x a ex. 3 x 6 = 6 x 3 = 18 Associative Law For Addition: (a + b) + c = a + (b + c) ex. (4 + 6) + 5 = 4 + (6 + 5) = 15 Associative Law For Multiplication: (a x b) x c = a x (b x c) ex. (2 x 3) x 4 = 2 x (3 x 4) = 24 Distributive Law: a x (b +c) = (a x b) + (a x ...
